IPC: C10B33/02
Filed: 1929-02-21
Abstract: 325,120. Rude, J. Feb. 21, 1929. Cooling discharged materials.-The dry cooling of coke in a container a is effected by the circulation, in a closed circuit, of steam of pressure above atmospheric, this pressure being permanently maintained by the provision of means to charge and discharge the chamber a without opening it to the atmosphere. As shown in Fig. 1, the hot coke is supplied to the chamber a from a hopper b fitted with alternately-operated valves d, f and with valve pipes h, i by which the interior of the hopper may be opened alternately to atmospheric pressure and the higher pressure prevailing within the chamber a. The latter, which is provided at its upper part with a water jacket u, communicates, through a continuously-operated rotary valve e, with a discharge hopper c provided with a door and a valved pipe j by which any pressure in the hopper may be released. The circuit for the cooling steam comprises a blower n, conduits m, o, and a chequer-brickwork evaporator l which is supplied with water through a valve k. A quantity of superheated steam equivalent to the steam added to the circuit by the evaporation of the water, passes off through the valve p and pipe q and is utilized for the production of water gas or for preheating the coal either before or after it is charged into the coking-retorts e, Fig. 2. The amount of water supplied to the evaporator l is controlled in accordance with the temperature of this excess steam by connecting the valve k to a thermostatic element r in the off-take pipe q. Fig. 2 shows a modification in which steam instead of water is introduced into the circuit, the evaporator l being replaced by a boiler v from which steam is led to the circuit through pipe y and pressure-reducing valve z. The amount of steam thus introduced is controlled in accordance with the steam pressure in the circuit, a valve i in the pipe y being connected to a pressureresponsive member d in the conduit m.

Title: Diisocyanate-modified polyester elastomers
IPC: C08G18/76
Filed: 1951-03-13
Abstract: Curable elastomers are prepared by reacting a linear polyester having an hydroxyl number from 40-100 and an acid number from 0 to 7, a bifunctional additive, containing at least one primary amino and/or carboxyl group, in an amount such that the total number of primary amino and carboxyl equivalents in the additive is from 0.06 to 0.48 per mol. of polyester, and 4,41 - diphenyl diisocyanate, 4,41 - diphenylene methane diisocyanate, dianisidine diisocyanate, 4,41-tolidine diisocyanate, 1,5-naphthalene diisocyanate, 4,41-diphenyl ether diisocyanate or p-phenylene diisocyanate in an amount equal to the sum of 0.70 to 0.99 mols. of diisocyanate per mol. of polyester plus a molar amount of diisocyanate equivalent to the molar quantity of bifunctional additive used.  The additive may be a diamine, amino-alcohol, amino-acid, dicarboxylic acid, hydroxy carboxylic acid, or a urea, thiourea or guanidine containing a primary amino group and may be added after the polyester and diisocyanate have been partially reacted.  The products cure in a shorter time than if the additive were not included and the cured products are free from blisters.  The polyester may be in part derived from unsaturated components such as fumaric, maleic, dilinoleic and dihydromuconic acids in which case, sulphur, benzoyl peroxide or t.-butyl hydroperoxide may be used as curing agents. Other curing agents specified are di- and other poly-isocyanates and alkyl ethers of hexamethylol melamine with a 2,4-dihalo naphthol as accelerator.  The quantity of polyisocyanate used for curing should be such that the total number of isocyanate equivalents present in the cured product is equal to the sum of 2.8 to 3.2 per mol. of polyester plus twice the molar amount of additive used.  Curing is preferably effected by dry heat, hot water or steam resulting in partial degradation. The Specification lists many compounds suitable as the bifunctional additive and also for making the polyester and also gives many examples of starting mixes for the polyester.  In an example a polyester having an hydroxyl number of 58.6 and an acid number of 3.5 and derived from adipic acid, ethylene glycol and propylene glycol was reacted with 1.07 mols. of 4,41-diphenyl diisocyanate and 0.12 mols. hexamethylene diamine per mol. of polyester at 130 DEG  C. for 8 hours.  In similar examples, adipic acid and ethanolamine were used instead of hexamethylene diamine. All three modified polyesters were cured by reaction with 0.55 mols. of additional 4,41-diphenyl diisocyanate per mol. of polyester at 300 DEG  F. for 30 minutes. Polymers prepared without the additive blistered on curing unless they were partially cured, remilled and then finally cured. Specifications 553,733 and 694,982 are referred to.

Title: Improved device for automatically feeding material in strips to presses, punching machines and the like
IPC: B21D43/11
Filed: 1921-02-22
Abstract: 178,649. Schuler, A. Feb. 22, 1921. Feeding webs.-A reciprocating - gripper device for feeding strip material to presses, punching- machines, &c. is arranged so that the length of feed is independent of the closing of the grippers and consequently of the thickness of the material. The device comprises a sliding carriage 1 to which is pivoted a lever 3 connected to the operating-rod 5, which is actuated from the machine in the usual way. A bolt 6 in the carriage is provided with a locking- wedge 7, turning movement being applied thereto, to open and close the grippers, through the medium of a lever 8 which is acted on by a spring 12 connected to a hook 13 on the carriage, so that normally the wedge 7 is drawn into engagement with an intermediate pivoted member 11 to grip the strip 2. When released, the member 11 is withdrawn from engagement with the strip by a spring 10. When the idle stroke of the operating-rod 5 commences, an extension 3<a> of the lever 3 acts on the lever 8 to cause the gripper to release the strip, but the carriage 1 is not moved back until the lever 8 is forced into engagement with a stop 1<a>. When the feeding-stroke begins, the lever 8 is released from the action of the part 3<a> and is pulled by the spring 12 to cause the strip 2 to be gripped between the carriage and the member 11. Movement of the carriage only begins when an extension 3<b> of the lever 3 seats itself on the carriage 1. The spring 12 must be less strong than the braking force of the carriage to allow the grippers to be opened before the return movement of the carriage commences.
